A set of 13 coal slurry fuels was prepared and combusted in a precombustion chamber compression ignition engine in the National Institute for Petroleum and Energy Research laboratory. The fuels consisted of five different coals with varying ash and volatility content in the liquid carriers: diesel fuel, methanol, water, and a blend of water and methanol. The fuels were prepared to a specification of 45 weight-percent solid coal, a maximum coal particle size of 20 micrometers, and a Brookfield viscosity of less than 1,500 centipoise. The 5-1/8-inch bore single-cylinder engine was operated at a compression ratio of 16.5:1 at 800, 1,000, and 1,200 rpm with pilot injection and glo-plug ignition assist, where necessary, at 1/4, 1/2, and full load data points. The project is described, the test logic discussed, and a summary of the findings is presented.
